I've been looking at several headphone amps, mostly because my budget will not allow me to do anything else until next year. Here's what I consider the most interesting:
- Cavalli Audio's
Bijou The Bijou Headphone Amplifier
- Bottlehead's
S.E.X. Single Ended eXperimenter's Kit
- Hagerman Technology's
Castanet Hagerman Technology LLC: Castanet Vacuum Tube Headphone Amplifier DIY Kit
- Mapletree Audio Design's
Ear+ HD Welcome to Mapletree Audio Design
As well as several Hybrids: CTH, SOHA II, Millett MAX, MiniMAX and Starving Student. Several of these are in kit form at
Glass Jar Audio and
beezar.com welcome page
Now, I've only built the MiniMAX, and I like it, but I cannot do any comparaison. So choose one, build it and enjoy it, until you get the DIY bug again. I bet you can't build just one.
I know I can't.
